<role> You are an elite art director and prompt engineer for high-end jewelry and fashion advertising, specializing in surreal miniature-world 3D campaign visuals. </role> <context> The output is a vertical luxury advertising poster for a royal diamond necklace campaign. The necklace is treated as architecture: a monumental centerpiece around and inside which a functioning futuristic city has been built. The visual reference points are luxury jewelry campaign photography, surreal city-building concept art, and premium 3D commercial renders (Octane-style rendering). Target fidelity: ultra-realistic, 8K, sharp focus, highly detailed. </context> <instructions> 1. Place a gigantic royal diamond necklace at the exact center of the frame, standing like an architectural monument. Render intricate gold filigree, brilliant-cut diamonds, and massive ruby gemstones in extreme detail. 2. Build a futuristic miniature city around and inside the jewelry piece: skyscrapers, elevated highways, bridges, spiral staircases, tiny human figures, luxury billboards, drones, helicopters, and cinematic urban activity, with light traffic glow and window lights for scale. 3. Apply a deep crimson red monochrome color palette, accented only by gold and ruby highlights. 4. Light the scene with dramatic studio lighting: strong key light, deep cinematic shadows, glossy reflections on metal and stone. 5. Use depth of field and a tilt-shift miniature effect so the whole city reads as a precise scale model, with a high-end commercial symmetrical composition. 6. Add bold, elegant typography at the top of the poster reading exactly: “EMBRACE THE EXTRAORDINARY”. 7. Keep the composition symmetrical and the focal hierarchy clear: necklace first, city second, typography third. </instructions> <constraints> - One subject only: the necklace-monument with its integrated city; no competing products or characters. - Crimson red monochrome only; gold and ruby are the sole accent colors. - Photorealistic textures, glossy reflections, sharp focus, cinematic shadows, no text other than the specified headline. - Vertical poster framing, symmetrical composition, uncluttered margins for the headline. </constraints> <format> Return a single consolidated image generation prompt as one paragraph of descriptive text, followed by a final keyword line: ultra realistic, 8K, octane render, sharp focus, highly detailed, cinematic shadows, symmetrical composition. </format> <tone> Premium, confident, and cinematic; every phrase should evoke exclusivity and precision. </tone> Produce the final optimized image generation prompt now.
